The video tutorial covers the basics of histograms and frequency tables. It explains how to interpret numeric data using histograms, defines frequency and mode, and demonstrates how to fill a frequency table from a histogram. The tutorial also guides viewers on creating a histogram from a frequency table and analyzing data to answer questions about student ages and frequencies.

What does 'frequency' in a histogram represent?

• The width of each bar

• How often a data point occurs

• The range of data values

How do you find the percentage of a category in a frequency table?

• Multiply the category's frequency by 100

• Divide the category's frequency by the total frequencies
